B and D assistance

I found a few new resources/tips for students who frequently reverse b and d. First of all, you can make the b with left hand and the d with the right hand or make a cicle with your thumbs and pointer fingers for the b/d on each hand. I also like the tip of reminding a student that a lower case b is in a upper case B and that a d follows a c so make a c and then form it to a d!
